Unhandled AbortError crash during stream generation in processTurn

[7hokerz]

What happened?

When using the gemini-cli, the application unexpectedly crashes with an unhandled AbortError.

Stack Trace:

AbortError: The operation was aborted.
    at abort (file:///C:/Users/.../node_modules/node-fetch/src/index.js:70:18)
    at AbortSignal.abortAndFinalize (file:///C:/Users/.../node_modules/node-fetch/src/index.js:89:4)
    at [nodejs.internal.kHybridDispatch] (node:internal/event_target:843:20)
    at AbortSignal.dispatchEvent (node:internal/event_target:776:26)
    at runAbort (node:internal/abort_controller:488:10)
    at abortSignal (node:internal/abort_controller:465:5)
    at AbortController.abort (node:internal/abort_controller:507:5)
    at GeminiClient.processTurn (file:///C:/Users/.../packages/core/dist/src/core/client.js:480:28)
    at processTurn.next (<anonymous>)
    at GeminiClient.sendMessageStream (file:///C:/Users/.../packages/core/dist/src/core/client.js:577:32)

What did you expect to happen?

The CLI should catch the AbortError (or signal.aborted state) during the asynchronous stream processing.
tead of crashing the entire Node.js process with an unhandled rejection, it should handle the interruption gracefully.
